It was used from 1992 until sometime around the late 1990s. It was replaced by “Guidelines for the Reproduction of the PAC-MAN Character”, a revised Pac-Man style guide from Namco's Japanese team featuring the new (unified) Japanese art style with artwork by Hideki Tanaami; issued in 1999, though the new artwork would begin to appear as early as 1996. The last notable Pac-Man production to use the designs is Pac-Man Ghost Zone, though some of the facial features from this manual (specifically for Pinky) would continue to be used for a few years past the replacement of this manual.
